Answer:

x=9.06

Step-by-step explanation:

We have the hypotenuse and we want the opposite of angle a.

so we do

sin65 = x/10.

Solve for x by simplifying both sides of the equation, then isolating the variable.

Write 2 as a complex number.

balandron [24]

Answer:

2 + 0i

Step-by-step explanation:

Our real number in this scenario would be 2. And since we don't need an imaginary part because we are just converting 2 by itself, we plug in 0 for the imaginary number.

A triangle has a perimeter of 72 units, and two of its sides measure x units and 3x units, respectively. Which inequality repres

blagie [28]

Answer:

$x$

Step-by-step explanation:

Given: Perimeter of triangle= 72 units

Measure of one of the side= x units

Measure of second side = 3x units

We know the perimeter of triangle is equal to sum of all sides.

Now, finding the possible value of x

forming an inequality to determine the value of x

Remember triangle has three sides, however, measure of only two sides are given.

⇒ $x+3x < 72\ units$

⇒ $4x$

Dividing both side by 4

⇒ $x < 18$

∴ The inequality to represents all possible values of x is $x < 18$

Using interval notation , identify the domain for the function!!! Math 3 - 10 points. Help needed

In-s [12.5K]

Answer:

The domain by the interval notation is (-∞ , 3)∪(3 , 4)∪(4 , ∞) ⇒ 3rd answer

Step-by-step explanation:

* Lets revise how to find the domain of the function

- The domain is all values of x that make the expression defined

- To find where the expression is undefined put the denominator

equal 0, to get the values of x which make denominator equal to 0

- The domain will be all the real number except those values

* Now lets solve the problem

∵ f(x) = (x² - 9)/(x² - 7x + 12)

- Let the denominator x² − 7x + 12 equal to 0

∵ x² − 7x + 12 = 0 ⇒ factorize it

- Consider the form x² + bx + c

- Find a pair of integers whose product is c and whose sum is b

- In this case, whose product is 12 and whose sum is −7

- They are -3 and -4

- Write the factored form using these integers.

∴ (x -3)(x - 4) = 0 ⇒ put each bracket = 0

∴ x - 3 = 0 or x - 4 = 0

∵ x - 3 = 0 ⇒ add 3 to both sides

∴ x = 3

∵ x - 4 = 0 ⇒ add 4 to both sides

∴ x = 4

∴ The domain of f(x) is all real number except 3 and 4

* The domain by the interval notation is

(-∞ , 3)∪(3 , 4)∪(4 , ∞)
